Summary: The purpose of this paper is to show the capabilities developed out of two Navy
(NAVAIR and ONR) Small Business Innovative Research Programs for the application
of high power semi-conductor diode lasers (HPDL’s) for surface preparation of aircraft.
The paper will show specific examples of coatings removal of epoxy and polyurethane
coatings and appliqué coatings from aluminum skins, composite and fiberglass surfaces.
Specific examples of test results of HPDL’s for surface preparation of aluminum,
composite and fiberglass surfaces as found on Navy aircraft will be shown, such as
radome coatings removal. Material tests and performance results specifically related to
long term (5X) testing on 2024-T6 aluminum and composite panes will be presented. The
processes and equipment, both portable and fixed will be described, as well as application
to Navy uses and requirements both in new construction of aircraft as well as in the
maintenance of active and aging aircraft. Environmental testing of the effluent/waste by
products will be presented along with the economic, energy efficiency, environmental
and performance advantages of HPD Laser technology for will also be described.
